My problems were similar to those reported above: the computer sometimes crashed on boot. When it did manage to boot the mouse was often frozen and other things as well did not function, such as volume control from the keyboard. Programs either did not run or malfunctioned when run.

I had the same freezing issue on my i5-8250U laptop since I've upgraded the kernel to 4.15.0-151 via apt upgrade. The freeze happened 3x in the morning, once while working in desktop, then twice on the lightdm logging screen. The mouse and keyboard completely froze, all I could do was to turn the laptop off via power button. The temporary fix was to power-cycle and use kernel 4.15.0-147 via grub menu. I installed the test kernel 4.15.0-153 from Juerg, and so far it seems to fix the issue for me. I did 10 restarts, logging to desktop and starting firefox on this web page. I also did 2 complete power-offs and some compilation as well in between. No issue so far, looks promising. Thanks for checking the issue.

[Bug 1938013] Re: 4.15.0-151 is freezing various CPUs
A test kernel is available here: https://kernel.ubuntu.com/~juergh/lp1938013/ We'd very much appreciate it if people could do some testing. Download the debs and install them with 'dpkg -i *.deb'. The kernel is unsigned so secure boot needs to be disabled. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938013 Title: 4.15.0-151 is freezing various CPUs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1938013/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

In my case it froze everytime "wlp4s0: WPA: Group rekeying completed with ..." appeared in the logs or if I manually connected to the wifi. Disabled ipv6, didn't crash so often anymore and not on each manual connect anymore. But still had some freezes (especially if the CPU load changed abruptly), until I switched to the 147 kernel. In logs I saw the kernel page error and also that the CPU throttled shortly before the crashes. Not sure if this helps to pinpoint the exact cause. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938013 Title: 4.15.0-151 is freezing various CPUs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1938013/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I did encounter the issue on a Lenovo Thinkpad P50 with an Intel wifi adapter. At the time of the freezes and crashes the ethernet cable connection was used - wifi on and configured, though. I leave it to your good judgement if the sketched scenario will also be covered by the fix.

We believe it's a memory corruption in the wifi stack (mac80211 module). Expect a test kernel soon. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938013 Title: 4.15.0-151 is freezing various CPUs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1938013/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
